CLARKE, resident of 171.Christopher Colum- Great Britain,

bus street, i'n the city and vdistrict of Montreal, in the Province of Quebec, in the Dominion of Canada, asubject of the Kingof have invented certain new and useful Improvements in Document- Files; and I do hereby declare that the following is a full,clear, and'exact descriptionof the same. e

The inventlon relates to improvements in I document files, as described in the present specification and illustrated "in the accompanying drawings, that form part of the Same.

The invention consists essentially in the novel arrangement and construction of the members and means for locking the same. a I

The objects of the-invention are to devise a file which will enable the user to upper portion of the cover.

keep the cover portion tightly down on the letters filed, at all times, to facilitate the renewal of the .posts of the file, and generally toprovide a slmple, cheap and convenient oflice device. i

In'the drawings, Figure 1 is a perspective view of the upper portion of the file showing a' cover standing out from the back and the pests extendingthrough the-cover. Fig." 2 is a'pers 'ective detail of the'upper portion of the 'ack. Fig. 3 is a perspective detail. of the flexible bar of metal forming the posts. Fig. fl is a perspective detail of the perspective detail showing the loc ingbars and catch.

v Like numerals of reference indicate correspondmgparts 1n each figure.

-Referring to the drawings, 1 is char of flexible metal forming the posts of the file. I .2 is the back of the file havingthe pair of holes 3 through which the posts extend and a pair of holes 4 through which said post bar 1- is threaded to retain it in position.

5 are eyelets protecting the edges of the holes 35 It will. be seen that the bar of metal 1 is first inserted through. one ofthe holes 3 and then threaded through the holes 4 and the Specification of Letters i'atent. I I Application filed April 20, 1910. Serial No. 556,490.

14 are catches having the flanges 15 extending under the flanges 10 and slidin in said locking bar and stopped at each en by the lugs 11.

In the operation of this file, the letters are perforated as usual with a common perforating machine' and placed on the posts the post bar 1, these posts exfrom the back 2, the cover is then placed on the posts on to of the letters and the osts bent downwar ly and are run into the 00king bars 9'under the flanges 10, the catches are then slid over the ends of the osts and firmly secure said postsin sald 100 What I claim as my invention is:

In a document file, a back having a pair of holes suitably spaced and eyelets protecting the edges of said post holes and'a pair of holes arranged between said post holes, a-

bar of flexible metal inserted through one of said post holes and threaded through the' post ends of the flexible bar and locking ing bars f and hold the letters firmly between the cover and the back.

lateral flanges extending underthe flan es t k of said locking bars' and adapted to slfde ALBERT GEORGE 5 over the post ends of said flexible bar and" Witnesses:

lock the same in said channeled bars. 7 G. H. Tnnsmnmz;
